Technical Team/Use Cases/2.0/Provide sufficient data to allow consumer to comply with licenses on redistribution

1. Title: Provide sufficient data to allow consumer to comply with licenses on redistribution
2. Primary Actor: Consumer who would like to redistribute
3. Goal in Context: To include sufficient information to allow the consumer to comply with licensing on redistribution. Note: We are not telling the consumer *how* to comply, just providing information sufficient to comply based on their interpretation of the licenses.
4. Stakeholders and Interests:
   1. Consumers of copyrightable artifacts:
      1. To receive accurate and clear information of licensing of artifacts
      2. To be able to comply easily with licenses for artifacts
      3. To be able to subset, extend, or aggregate artifacts and pass on clear authoritative verifiable license for the resulting new copyrightable artifacts.
5. Preconditions:
   1. Consumer has a policy about how to comply with a given license, or the capacity to develop one.
6. Main Success Senario: Consumer is able to comply with license on redistribution based on the SPDX data.
7. Failed End Condition: Consumer is not able to comply with license on redistribution based on the SPDX data.
8. Trigger:
   1. Receipt of a new copyrightable artifact(s).
9. Notes: Review attached example required contract clause proposed by Alcatel-Lucent to their suppliers. We note that SPDX 1.x model may not adequately support tying together licenses and required attributions of copyright holders, for example.
